A control group study of incubators’ impact to promote firm survival

It is widely unclear as to whether start-up firms supported by publicly-initiated incubator initiatives have higher survival rates than comparable start-up firms that have not received support by such initiatives. This paper contributes to the underlying discussion by performing a large-scale matched-pairs analysis of the long-term survival of 371 incubator firms (after their graduation) from five German incubators and a control group of 371 comparable non-incubated firms. The analysis covers a 10-year time span. To account for the problem of selection bias, a non-parametric matching approach is applied to identify an appropriate control group. For neither of the five incubator locations, we find statistically significant higher survival probabilities for firms located in incubators compared to firms located outside those incubator organizations. For three incubator locations the analysis reveals statistically significant lower chances of survival for those start-ups receiving support by an incubator. The empirical results, therefore, raise some doubts regarding the impacts of incubation on long-term firm survival.     

Reasons underlying treatment preference: an exploratory study

Very little is known about what factors influence women's treatment preferences after a sexual assault. To learn more about these factors, data were collected from 273 women who read a standard "if this happened to you, what would you do" scenario describing a sexual assault and subsequent trauma-related psychiatric symptoms. After reading standardized treatment options for a pharmacotherapy (sertraline) and a psychotherapy (cognitive behavioral treatment), participants made a hypothetical treatment choice and reported the main reasons for their choice. Women often cited reasons surrounding the effectiveness of a treatment as the primary reason for their treatment preference, suggesting potential masking of symptoms with the medication and more logical, long-lasting effects with the psychotherapy. Other common reasons underlying treatment preference were wariness of the medication and positive feelings about talking in psychotherapy. Better understanding factors that influence treatment preference may aid in refining psychoeducation materials regarding the psychological consequences of sexual assault and their treatment for the lay public and in helping clinicians further tailor their discussion of treatment alternatives for these women.     

The Armenians of Los Angeles: Rethinking “Americanization”

Abstract

The existing scholarship typically measures “Americanization” along structural lines—such as knowledge of public policies, percentage of life spent in the U.S., or proficiency in the English language. While these variables are certainly important, they overlook another important dimension of newcomers’ post-migration experiences—namely, immigrants’ psychological attachment and sense of belonging to the American social, political, and economic fabric. This article therefore reevaluates what it means to Americanize by exploring the psychological (or symbolic) dimensions of multigenerational immigrants’ evolving political beliefs toward the polity. In rethinking the process of Americanization, we rely on a largely understudied immigrant population—that is, the Los Angeles Armenians (or Armenian Angelenos)—and an original public opinion survey—the Armenian Angeleno Survey (AAS). This study demonstrates that symbolic (rather than merely structural) Americanization is a useful framework in studying how contemporary immigrant groups position themselves in relation to the polity and understand important political outcomes. This article thus introduces an expanded model based on how multigenerational immigrants cultivate their ethnic communities while becoming ideological members of American society.     

Characterization of deoxyribonucleic acid (DNA) obtained from teeth subjected to various environmental conditions.

This study was designed to determine the effects of various environmental factors on the deoxyribonucleic acid (DNA) obtained from dental pulp. Extracted teeth were subjected to the following conditions: varying pH (3,7,10); temperature (4 degrees C, 25 degrees C, 37 degrees C, incineration); humidity (20%, 66%, 98%); various types of soil (sand, potting soil, garden soil); seawater; burying the teeth outdoors, and aging (one week to six months). In addition, teeth that had been extracted and held at room temperature for 16 and 19 years were also examined. Following isolation of DNA, the samples were analyzed on yield gels to determine the concentration and integrity of the recovered DNA. Restriction digestion with Pst I was followed by electrophoresis of the generated fragments, Southern transfer to nylon membranes, and hybridization to both human and bacterial probes. It was determined that, aside from soil, the environmental conditions examined did not affect the ability to obtain high-molecular-weight human DNA from dental pulp. Restriction fragment length polymorphic (RFLP) analysis of selected samples was performed. Dental pulp patterns were compared with bloodstain exemplars, revealing matching patterns, although an increase in band-shifting was observed with extended exposure to elevated temperatures.     

Effective handling of health-related leaves of absence

This article will address the legal obligations of employers in non-union settings toward employees who request pregnancy leave, parental or medical leave, workers' compensation leave, and other forms of disability leave. Specifically, this article will address the legal standards set forth under the Pregnancy Discrimination Act, various state pregnancy and family leave acts, workers' compensation retaliatory discharge authority, and the Americans With Disabilities Act of 1990. In addition, this article will provide practical guidance for employers in formulating effective leave policies that provide the maximum amount of operational flexibility while at the same time minimizing the risk of costly and excessive litigation.
